Thanks so much! We have a SE that does server config. I'll talk to him about the my.cnf and httpd.conf settings. Do you have any recommendations for resources to optimize these for high load WordPress?
The server itself is pretty beefy I think, so I'm guessing it is more a configuration issue.

Lulu, we don't have access to each install of WordPress (central IT office). Departments manage their own installs for the most part. We can however recommend a caching plugin to decrease the loads.
